覆盖标准框架时如何在一帧上获得多个面板？

Question

我正在学习来自http://wiki.wxpython.org/Getting%20Started 的教程，并且正忙于笔记本示例。在这里，多个面板被添加到一个框架中。它使用以下示例代码：

class ExamplePanel(wx.Panel):
    def __init__(self, parent):
        [...]

app = wx.App(False)
frame = wx.Frame(None, title="Demo with Notebook")
nb = wx.Notebook(frame)

nb.AddPage(ExamplePanel(nb), "Absolute Positioning")
nb.AddPage(ExamplePanel(nb), "Page Two")
nb.AddPage(ExamplePanel(nb), "Page Three")
frame.Show()
app.MainLoop()

这对我有用。但是，我不想使用标准的 wx.Frame() 作为框架，而是使用自己的框架（如果我只使用一个面板，框架就可以工作）：

class ExampleFrame(wx.Frame):
    def __init__(self, parent, title):
        wx.Frame.__init__(self,parent, title = title)
        panel = wx.Panel(self)
        self.CreateStatusBar()
        # Setting up the menu.
        filemenu = wx.Menu()

        #wx.ID_ABOUT and wx.ID_EXIT are standard IDs provided by wxWidgets
        menuAbout = filemenu.Append(wx.ID_ABOUT, "&About", " Information about this program")
        menuExit = filemenu.Append(wx.ID_EXIT, "E&xit", " Terminate the program")

        # Creating the menubar
        menuBar = wx.MenuBar()
        menuBar.Append(filemenu, "&miP3") # Adding filemenu to the MenuBar
        self.SetMenuBar(menuBar) # Adding the MenuBar to the Frame content.

        # Set events
        self.Bind(wx.EVT_MENU, self.OnAbout, menuAbout)
        self.Bind(wx.EVT_MENU, self.OnExit, menuExit)     

    def OnAbout(self, event):
        # A message dialoge box with an OK button. wx.OK is a sandard ID in wxWidgets
        dlg = wx.MessageDialog(self, "Author: Niek de Klein", "About miP3")
        dlg.ShowModal() # show it
        dlg.Destroy() # finally destroy it when finished

    def OnExit(self, eevent):
        self.Close(True) # close the frame

app = wx.App(False)
frame = frame = ExampleFrame(None, title="Demo with Notebook")
nb = wx.Notebook(frame)

nb.AddPage(ExamplePanel(nb), "Absolute Positioning")
nb.AddPage(ExamplePanel(nb), "Page Two")
nb.AddPage(ExamplePanel(nb), "Page Three")
frame.Show()
app.MainLoop()

如何将多个面板添加到我的自定义框架中？

你可以这样做：

#!/usr/bin/env python
import wx
import wx.grid

class ExampleFrame ( wx.Frame ):

    def __init__( self, parent ):
        wx.Frame.__init__ ( self, parent)

        self.SetSizeHintsSz( wx.DefaultSize, wx.DefaultSize )

        bSizer1 = wx.BoxSizer( wx.VERTICAL )

        self.Panel = wx.Panel( self, wx.ID_ANY, wx.DefaultPosition, wx.DefaultSize, wx.TAB_TRAVERSAL )
        bSizer2 = wx.BoxSizer( wx.VERTICAL )

        self.nb = wx.Notebook( self.Panel, wx.ID_ANY, wx.DefaultPosition, wx.DefaultSize, 0 )

        bSizer2.Add( self.nb, 1, wx.EXPAND |wx.ALL, 5 )

        self.Panel.SetSizer( bSizer2 )
        self.Panel.Layout()
        bSizer2.Fit( self.Panel )
